What are you using? I'm having a tough time finding something I used to use (Kester, seems like it had a liquidus temp. of about 265�).

That might be the stuff. I think what baffles me is that it was readily available and packaged as "thermocouple attachment solder" or some such description, but they apparently don't seem to have it available by that name.

It's not a critical issue, but it does make me nervous to have another spool of solder that looks pretty much like every other spool we use in production.

Steve, your best solderer in your shop will know that this ain't standard wire solder. I always put the best solderer on T/C attachment duty when I have a scrap PCB to play with. They even have difficulty getting the stuff to wet to pads and leads.

Also, you might wanna check ECD and KIC's website. They sell the high-temp. stuff.

I also use a very high lead content solder for this. Its awful to solder with but works quite well once you have it on...
